Add another name to DNS server bind9

Question

I set up a DNS server using the bind9 utility, took the settings from the example, and this is how the configuration turned out:

file: /etc/bind/named.conf.local

//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

zone    "testing.net" {
        type master;
        file "/etc/bind/db.forward.com";
};

zone    "12.168.192.in-addr.arpa" {
        type master;
        file "/etc/bind/db.reverse.com";
};

file: /etc/bind/db.forward.com

;
; BIND data file for local loopback interface
;
$TTL    604800
@       IN      SOA     ns.testing.net. root.localhost. (
                              2         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      ns.testing.net.
ns      IN      A       192.168.12.1
server  IN      A       192.168.12.1
www     3600    IN      CNAME ns.testing.net.

file: /etc/bind/db.reverse.com

;
; BIND reverse data file for local loopback interface
;
$TTL    604800
@       IN      SOA     ns.testing.net. root.localhost. (
                              1         ; Serial
                         604800         ; Refresh
                          86400         ; Retry
                        2419200         ; Expire
                         604800 )       ; Negative Cache TTL
;
@       IN      NS      ns.
1       IN      PTR     ns.testing.net.
1       IN      PTR     ns.testing.net.

I have a service running on the system which is available by the name demo.testing.net. I also implement an access point on this system, clients connected to it can access the name ns.testing.net.

Could you tell me please, how do I set up a config in bind9 so that clients can access the system called demo.testing.net? What should be specified in the configuration files? Thank you very much!

Answer 1

For Linux hosts you should put the following in their /etc/resolv.conf:

nameserver 192.168.12.1
search testing.net

They should then test with:

ping demo

Don't forget to put the following line in /etc/bind/db.forward.com:

demo  IN      A       192.168.12.<host ip>

and in /etc/bind/db.reverse.com:

<host ip>     IN      PTR     demo.testing.net.

and restart your bind9 server.

Good luck.
